You can put this solution on YOUR website!
u need to use the point slope form to find the slope then use the slope intercept formula to find the intercept, then u will have the equation.
\n" ); document.write( "\"m=%28%28y-y%29%2F%28x-x%29%29\" (-4,4)(8,8) substitute
\n" ); document.write( "\"m=%28%284-8%29%2F%28-4-8%29%29\" subtract/add
\n" ); document.write( "\"m=%28%28-4%29%2F%28-12%29%29\" reduce
\n" ); document.write( "\"m=%281%2F3%29\"
\n" ); document.write( "_____
\n" ); document.write( "\"y=mx%2Bb\"
\n" ); document.write( "\"8=%281%2F3%298%2Bb\" multiply
\n" ); document.write( "\"8=%288%2F3%29%2Bb\" subtract
\n" ); document.write( "\"8-%288%2F3%29=b\" make subtractable fraction
\n" ); document.write( "\"%2824%2F3%29-%288%2F3%29=b\" subtract

\n" ); document.write( "\"y=%281%2F3%29x%2B%2816%2F3%29\"
\n" ); document.write( "this is the equation for the line that passes through those points.
